Academia, as many other sectors, has faced wide-ranging disruptions due to COVID-19, with teaching and research activity conducted entirely online in many countries. Before the pandemic grounded travel, academics were often hypermobile, some traveling more than 150,000 kilometers per year for conferences, board meetings, collaborations, fieldwork,seminars, and lectures. It is no surprise then that academic flying is among the leading causes of universities' greenhouse-gas (GHG) emissions. Despite growing awareness surrounding GHG emissions from flying and calls for reducing aeromobility, academics have continued to travel. The COVID-19 pandemic, in equitably stopping all flying, offers a unique opportunity to study emerging low-GHG modes of academic internationalization. In this article, we look at academic internationalization, inspired by digital ethnography, to explore how the academic landscape has adapted to meet internationalization goals within the context of a sudden grounding of travel. By investigating flight-free academic internationalization, we illuminate some of the implications and discuss potential opportunities and challenges of achieving less GHG intensive academic internationalization.
